Demo: IDEA reads multiplatform module dependencies as jars

README

If a (java) project depends on two kotlin-multiplatform libraries that depend on each other, 
this causes strange behaviour when importing the project in IntelliJ IDEA: the java-project
classpath gets a compile entry containing two jar files, pointing to the gradle build path
of the two libraries' jars (see `issue-jar-dependency.png`).

If the transitive dependency is comment out in the java-project dependencies, it gets imported
correctly, even though the transitive dependency is marked as "implementation" in the other 
libary (see `issue-module-dependencies.png`).

    id 'org.jetbrains.kotlin.jvm' version '1.3.11' apply false

    repositories {
        jcenter()

project('library1') {
    apply plugin: 'kotlin-multiplatform'

    kotlin { targets { fromPreset(presets.jvm, 'jvm') } }
}
project('library2') {
    apply plugin: 'kotlin-multiplatform'

    kotlin {
        targets { fromPreset(presets.jvm, 'jvm') }

        sourceSets {
            jvmMain {
                dependencies {
                    implementation project(':library1')
                }
            }
        }
    }
}
project('java-project') {
    apply plugin: 'java'

    dependencies {
        implementation project(':library1') // "works" if this line commented out
        implementation project(':library2')
    }
}
